What this trial studies

This study evaluates a surgically implanted functional electrical stimulation (FES) system designed to enhance exercise, standing, stepping, and balance in individuals with varying degrees of paralysis. Participants will undergo surgery to implant electrodes into the muscles of the trunk and legs, which are connected to a stimulator. Following implantation, patients will receive training in mobility skills using the FES system, along with a prescribed rehabilitation program. The study includes assessments of strength, balance, and functional abilities at multiple follow-up points after discharge.

Who should consider this trial

Good fit: Ideal candidates include individuals with low cervical or thoracic spinal cord injuries or other paralyzing conditions who meet specific inclusion criteria.

Not a fit: Patients with certain medical conditions such as pacemakers, uncontrolled seizure disorders, or significant psychological issues may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve mobility and quality of life for patients with paralysis.

How similar studies have performed: Other studies have shown promise with similar functional electrical stimulation approaches, indicating potential for success.
